Journal ArticleDOI
Viscoelastic parameter identification of human brain tissue.
TL;DR: Rheological differences suggest a different porosity between both tissues and explain-at least in part-the ongoing controversy between reported stiffness differences in gray and white matter.
Journal ArticleDOI
Computational stress-deformation analysis of arterial walls including high-pressure response.
TL;DR: This model approach may be useful to improve interventional protocols for reducing the dilatational trauma, and thereby the adverse biological reaction in arterial walls following balloon angioplasty.
Journal ArticleDOI
A calcium-driven mechanochemical model for prediction of force generation in smooth muscle
TL;DR: The proposed model satisfies the second law of thermodynamics and is straightforward for implementation into a finite element program in order to solve more complex boundary-value problems such as the control of short-term changes in lumen diameter of arteries due to mechanochemical signals.
Journal ArticleDOI
A model for saccular cerebral aneurysm growth by collagen fibre remodelling
TL;DR: The first structural model for saccular cerebral aneurysm growth is proposed, which is able to predict clinical observations and mechanical test results, for example, in terms of predicted aneurYSm size, shape, wall stress and wall thickness.
Journal ArticleDOI
Smooth muscle contraction: mechanochemical formulation for homogeneous finite strains.
TL;DR: A mechanochemical finite strain model is formulated by considering the interaction between mechanical and biochemical components of cell function during activation and the dependence of muscle contraction (Ca2+-concentration) on active stress and related stretch.
